Tay Sachs Disease

Tay-Sachs disease (TSD) is a fatal genetic disorder, most commonly occurring in children, that results in progressive destruction of the nervous system. Tay-Sachs is caused by the absence of a vital enzyme called hexosaminidase-A (Hex-A).

What is Tay-Sachs Disease?

Tay-Sachs disease (abbreviated TSD, also known as GM2 gangliosidosis or Hexosaminidase A deficiency) is an autosomal recessive genetic disorder. In its most common variant known as infantile Tay-Sachs disease it presents with a relentless deterioration of mental and physical abilities which commences at 6 months of age and usually results in death by the age of four.

New gene therapy shows promising results for treating neurodegenerative disorders

A new gene therapy approach designed to replace the enzyme that is deficient in patients with the inherited neurodegenerative disorders Tay-Sachs and Sandhoff diseases successfully delivered the therapeutic gene to the brains of treated mice, restored enzyme function, and extended survival by about 2.5-fold.

Mutation that increases sphingolipid levels can lead to neurodegeneration

A mutation that increases the level of a special class of sphingolipids--molecules important to cell structure and signaling--can lead to neurodegeneration due to problems with neuronal membranes, reports a research team led by Jackson Laboratory Research Scientist Lihong Zhao, Ph.D. and Professor Patsy Nishina, Ph.D.

Counsyl, ARUP partner to expand pregnancy genetic test offering for prospective parents

Counsyl has partnered with ARUP Laboratories, a nonprofit enterprise of the University of Utah, to expand its pre-pregnancy and early pregnancy genetic test offering for prospective parents. ARUP's molecular genetic testing laboratory already provides a comprehensive set of testing options for a broad range of inherited disorders.

Statistical method uses evolutionary information to enhance identification of disease-associated alleles

A book containing misprints may cause annoyance for the reader, but typos in an individual's genetic blueprint (DNA) can mean serious disease or even death. The search for genetic correlates for the wide range of diseases plaguing humankind has inspired a wealth of research falling under the heading of genome-wide association studies (GWAS).

New genetic testing technology for IVG embryos

Researchers at the Johns Hopkins University School of Medicine have devised a new technique, which helps couples that are affected by or are carriers of genetic diseases have in vitro fertilized babies free of both the disease in question and other chromosomal abnormalities. The results were reported in the April issue of Fertility and Sterility.
